When web scraping in Python, it's essential to consider ethical implications, such as respecting the website's terms of service and robots.txt file, which outline permissible scraping practices. Avoid overloading servers with excessive requests, as this can disrupt service for other users. Always ensure that the data collected is used responsibly, especially if it involves personal information. Additionally, consider reaching out to website owners for permission when scraping large volumes of data to foster transparency and goodwill.
